Initially the aircraft Douglas DC-4 was developed based on the model Douglas DC-4E, as a multi-purpose aircraft, in particular, given the fact that the design of the aircraft began in the early 40-ies of the last century, the aircraft actively participated in the transportation of cargo and military contingent, and after the second World war, the aircraft began to be used by many civilian airlines as a means of passenger transport over distances of up to 6,8 thousand kilometers.

The power plant of the aircraft Douglas DC-4 represented by four piston engines, providing a total power of 5800 hp, as well as the flight speed in 450 km \ h (the maximum speed of flight), which makes it quite competitive even with the current models of this type. Nevertheless, the production of airplanes Douglas DC-4 was limited - within five years of release, only 80 aircraft were built, of which, at the end of the year 1945 used in civil aviation in all 47 aircraft.

On board the Douglas DC-4 can accommodate up to 40 80 people (depending on the cabin configuration) that provides justifiable operation of these aircraft in the local and regional routes. However, currently operates only a few aircraft of this model - the latter two aircraft are in use belong to African airlines'South African Airways"That is supposed to write off up to 2017 years.

Despite the fact that the plane Douglas DC-4 before actively used by air carriers around the world to manage the aircraft hard enough, thus, it is noted that because of the noisy aircraft engines Pratt & Whitney R-2000, the comfort of make flights is virtually absent, although, taking into account the production of aircraft, the passenger compartment is made sufficiently high quality, and is quite suitable even for the length of the route.

In addition to the basic production version, there is also a model and modified - CanadaAir North Star, the main difference of which is less powerful, but much simpler to operate and maintain aircraft engines Rolls-Royce Merlin G, capable of developing power 1030 hp each. However, the release of this modification has been very limited.

Among other things, based on the model of Douglas DC-4 subsequently these planes were built as Douglas C-54 SkymasterActively used by the US Air Force during the conduct of hostilities during the Second World War.
